But Holly has gone to great lengths to rubbish the speculation after telling how her boyfriend watches every performance of hers on the front row and last weekend she even posted a cosy snap of her with Kara backstage to end rift rumours.

Last night was the latest public display of affection for her boyfriend she’s made to try and stop the gossipmongers.

Oozing sex appeal in a skintight leather dress with mesh detail on the neckline and a pair of sky-high stilettos, Holly didn’t let go of her property tycoon billionaire boyfriend’s arm as she smiled her way through the crowds.

She had earlier tweeted: ‘So proud and excited to go to my Darling Nick’s book launch tonight for Candy & Candy- ‘The Art of Design’!! I ♥ You. #BeyondProud X’

And Nick, 38, also tried to put an end to the hearsay surrounding his girlfriend and Artem by shaking hands with him and sharing a joke as they posed for photographs. Kara was noticeably absent from the event.

Holly’s boyfriend Nick also had the support of other Strictly Come Dancing stars including Lulu, who seemed to be feeling the chill on the night, and Nancy Dell’Ollio who went for old-style glamour.

But it seems by the time the end of the night arrived, despite still looking just as glam as when she first arrived, Holly was a little worse-for-wear.

This was confirmed on her Twitter page this morning when she tweeted she was nursing a bag hangover while enjoying the day at a theme park.

‘If u could think of the worst thing 2 do w/a hangover, I’d say -“A theme park, in the rain, on school holidays, at 9am.” #ijustdidthat,’ she wrote.
